Hi KB, in the strictest sense of the word, scrambling routinely "does" take place on data facilities in order to create an equal number of ones and zeros on the line, and in many other parts of the network. This tends to maintain a balanced distribution of energy. Without this a line facility might become biased to either a positive or negative charge, relative to earth ground -which is undesirable for the artifacts, most notably errors on the line, that such would create. In some situations (such as digital data services over metallic loops, or on metallic T1 carrier facilities) this is referred to as the preservation of "ones densities."
